FIRE-ESCAPE.

Specification of Letters Patent.

Patented June 9, 1914.

App1ication filed October 11, 1912. Serial No. 725,235.

To all whom it may concern:

Be it known that we, FRANK J. BALDWIN and ELMER Tnnrson, citizens of the United States, residing at Galion, in the county of Crawford and State of Ohio, have invented new and useful Improvements in Fire-Escapes, of which the following is a specification.

This invention relates to fire escapes and the principal object of the invention is the provision of a device of this character which may be folded to compact form for transportation or storage and which may be set up for operation within a short period of time.

A further object of the invention is to provide a simple and efiicient device of this character employing a single drum with op positely wound cables thereon whereby the person being lowered by the first cable raises the second cable to operative position for a second operation.

A still further object of the invention is the provision of means for regulating automatically the speed of descent of the person from the fire zone to the ground.

Further objects of this invention will appear as the following specific description is read in connection with the accompanying drawings which form a part of this application, and in which Figure 1 is ing applied to the window frame of a building. Fig. 2 is an enlarged perspective view showing the supporting rod and its associated parts. Fig. 8 is a vertical sectional view taken on the line 3-3 of Fig. 1 and showing the drum supporting arm and associated parts in side elevation. Fig. 4: is a vertical sectional view through the drum frame and regulating cylinder. Fig. 5 is an enlarged transverse sectional view through the regulating cylinder. Fig. 6 is a detail elevation of the piston head. Fig. 7 is a similar view of the regulating disk which is carried thereby.

Referring more particularly to the drawings, 1 represents a substantially U-shaped frame whose legs 2 and 3 are braced apart by a cylinder guiding rod l and by the drum shaft 5. Extending between and secured to the legs is a piston rod 6 upon which is slidably mounted a cylinder 7 having a ring or collar 8 to slidably engage the rod 4 and thereby prevent the rotation of the cylinder and at the same time guide an elevation of the device he.

the same. The rod 6 carries a piston head 9 which is provided with a plurality of apertures 10 adapted to register with similar apertures 11 in a fluid adjusting disk 12 slotted at 13 to receive set screws 14; which hold the disk in adjusted position upon the piston head whereby the channels through the apertures 10 and 11 may be regulated as to size. The cylinder is preferably filled with oil or other similar material but may be filled with'air or any other fluid which will give the required resistance to the cylinder in its lateral movement over the piston rod 6.

Mounted upon the shaft 5 is a drum 15 which is separated into separate cable re ceiving portions by a disk 16 whose periphery is waved as shown at 17 and is engaged by the depending lugs 18 formed on the bottom of the cylinder. found around the drum in opposite directions and on opposite sides of the disk 16 are cables 19 and 20 both of which are preferably provided with body straps or other similar devices as is found most desirable. The frame 1 with its accompanying parts is secured to a window frame or other similar portion of the building in any suitable manner preferably by the device to be hereinafter described so that the persons may readily lower themselves by means of the cables when necessary.

Referring to the structure shown in Fig. 2, 21 and 22 show the separate window frame engaging rods each of which are sharpened at their outer ends as shown at 28 so as to permit them to enter the window frame and provided with limiting fingers 24 which facilitate their engagement with the window frame. The member 21 is provided with a plurality of sockets or recesses 25 while the member 22 carries a ring 26 having an inward projection 27, this rin is adapted to slide over the member 22 an have its projection 27 engage the apertures of the recesses 0r sockets 25 in the member 21. The member 21 is also provided with a tapered end 28 and the member 22 has a ring 29 slidably mounted thereon adapted to be positioned upon the tapered end and to bind thereon so as to hold themembers 21 and 22 in alinement. By engaging the projection 27 of the ring into one of the sockets when the ends of the members 21 and 22 are engaged in the frame and out of alinement and forcibly alining the members,

the sharpened ends of the members 21 and 22 are forced into the frame and the ring 29 is then slipped over the tapered end 28 so as to lock the members 21 and 22 in position. J ournaled upon the member 21 is a supporting arm 30 having a. hook 31 formed on one end and adapted to engage a loop 82 carried by the end of the frame 1, the opposite end of the arm 30 is provided with a hand hold 33 and with a hook revolubly mounted thereon s0 sition to engage the window in Fig. 3.

When the structure shown is mounted in the window frame as shown in Figs. 1 and 2 the U-shaped frame and its associated parts is mounted upon the arm by engaging the loop 32 in the hook 31. Persons desiring to escape from the burning building may then support themselves upon one of the cables 19 or 20. The uniform reciprocating motion of the cylinder as actuated by the as to be in posill as shown disk and as controlled by the regulating plate 12 and the oil in the cylinder prevents too rapid descent of the person using the re escape.

Having thus described the invention, what we'claim as new, is

1. In a fire escape, a reel frame, a reel journaled in the frame and having a disk separating the same into different cable receiving portions, said disk having a waved periphery, a piston rod secured in the frame and carrying a stationary piston head, a cylinder surrounding the piston head and slidably mounted upon the rod, means for operatively connecting the cylinder and disk whereby when the reel is rotated the cylinder Will be reciprocated, and cables Wound on the reel in opposite directions.

2. In a fire escape, a reel frame, a reel 34 reciprocatingly and journaled in the frame and having a disk separating the same into different cable receiving portions, said disk having a waved periphery, a piston rod secured in the frame and carrying a stationary piston head, a cylinder surrounding the piston head and slidably mounted upon the rod, means for operatively connecting the cylinder and disk whereby when the reel is rotated the cylinder will be reciprocated, and means for preventing rotation of the cylinder and for guiding the movement of the same.

' 3. In a fire escape, a reel frame, a reel jonrnal ed in the frame and carrying a waved disk, a piston rod secured in the frame and carrying a stationary piston, a slidably mounted cylinder to slide upon the piston rod and encompassing said piston head, said piston head being apertured and an adjustably mounted apertured disk carried by the piston head for regulating the passage of fluid therethrough together with means for operatively connecting the cylinder and waved disk.

4. In a fire escape, a reel frame, a reel journaled therein, a controlling mechanism mounted in the frame, means dividing the reel with separate cable receiving portions and coacting with the controlling mechanism to regulate the speed of the reel in either direction of movement and cables wound on the separate portions of the reel in opposite directions.

In testimony whereof we afiix our signatures in presence of two witnesses.
